OESA-2026-4147 (CVE-2026-30754)
Vulnerability from osv_openeuler – Published: 2026-09-30 13:47 – Updated: 2026-09-30 13:47 – Source websiteFFmpeg is a complete and free Internet live audio and video broadcasting solution for Linux/Unix. It also includes a digital VCR. It can encode in real time in many formats including MPEG1 audio and video, MPEG4, h263, ac3, asf, avi, real, mjpeg, and flash.
Security Fix(es):
A memory corruption vulnerability exists in FFmpeg before 8.1. The RTP encoding process. In the nal_send function in libavformat/rtpenc_h264_hevc.c, a negative size parameter (size=-3) is passed to memcpy when transmitting H.264/HEVC streams via RTP using a crafted input file. This was detected using AddressSanitizer.(CVE-2026-30754)
FFmpeg before 9.0 has an out-of-bounds read because of missing required padding in WMA extradata allocation paths in libavcodec/wmaenc.c.(CVE-2026-52296)
A vulnerability has been found in FFmpeg up to 4.4.6/5.1.8/6.1.4/7.1.3/8.0.1. Affected by this issue is the function setup_3x3 of the file libavfilter/vf_convolution.c of the component Convolution Filter. Such manipulation leads to out-of-bounds read. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 4.4.7, 5.1.9, 6.1.5, 7.1.4, 8.0.2, 8.1.1 and 9.0 can resolve this issue. The name of the patch is 8970658472/e24b9820b4. It is suggested to upgrade the affected component.(CVE-2026-90815)
